Transvenous closure of patent ductus arteriosus in a sick 2780g infant.

A three-and-a-half-month-old 2780 g critically ill infant had successful transvenous coil occlusion of a ductus arteriosus. At six-and-a-half months of age the infant died, and autopsy showed coverage of the coil on the aortic aspect and no lumenal narrowing. It was concluded that transvenous coil occlusion of the patent ductus arteriosus in small infants is possible and that th venous route is preferred to be arterial route.
